Sometimes it goes deeper than R and D. They also oversample women. Easier to hide. The recent PPP poll showing Obummer up +5 in Ohio not only oversampled Dems +4, but also oversampled women +9.

Wow, that’s really some good information. I knew about the party weighting but sex?!?!?! Where would all the men have gone? /s
Like your ID --- "Goodbye Mr.Chips" ---great movie!
Not to be a nitpicker, but the oversampling of women was 54% to 46%, or 8%. The 2010 census showed women outnumbering men by about 1.6%, so the PPP oversample of women is actually 6.4%, and that should definitely skew results in Obama’s favor since he always seems to poll stronger with women (Rush’s arousal gap).
The question is whether this oversampling of women is deliberate or a side effect of discarding republican responses to reach the desired R/D mix, which are more likely to have come from men.
But, I agree, any time someone has to decide whether to keep or toss a given sample, there is the potential for mischief.
